I suspect whatever's keeping you on Windows isn't really the network effect. It's usually: comfort level/personal preference, or a set of software that vendor(s) can't/won't port to another non-Windows platform.
The fact that so many applications have been rewritten as browser-accessible services has liberated me. I haven't owned a system with a Microsoft OS since ~2004 or so.
Tools like teams and outlook are also just not as good on Linux, and really important for work.
Is that not the network effect? I.e. everyone uses Windows so developers target their software for Windows, so everyone uses Windows?
The Windows division is another story though. With all the Windows 11 news I decided to give desktop Linux a spin for the nth time in 20 years. Installed Manjaro and I'm extremely impressed. Even though I have Nvidia graphics everything is buttery smooth, all my productivity tools are there, setting up my VPN was far easier than Windows, and even more amazingly most of my games work well thanks to the recent push by Valve and the steam deck.
I will probably stick with it this time, so maybe for me 2021 finally is the year of the Linux desktop.
I get that if you often need to switch it can be a pain in the ass but at least Linux respects my privacy and freedom.
VSTs are definitely an issue; most high quality commercial plugins are still only released for mac/windows. However there are a few projects for running them in wine and it generally works pretty well.
I do think we'll see more and more Linux in studios going forward, but it would help if Linux got its pro audio story together. Pipewire is a big step in the right direction but not yet mature.
The issue I had in mind was the unrestricted hardware access that Windows has if it is running natively. This is an operating system that has literally pushed updates that inadvertently deleted user data, among other severe problems, and that will deploy its updates automatically to many users. Dual booting won't ensure the integrity of your system against that kind of threat. Running Windows in a virtual environment means it can't damage the rest of your system even if it deploys a seriously broken update without warning. And that kind of virtualisation is getting more practical all the time even if for now it remains the preserve of serious Linux hackers.
It only played to their disadvantage, for machines with single storage device now doesn't boot Windows at all or only from VM.
To be honest, Microsoft astroturfers have long existed, for much more than 10 years.
Which is officially supported on Linux.
There might be reasons to run Windows, but this is not one :)
